| sometimes they come on after a certain amount of miles say, 80,000 100,000 130,000 ,just to get you in to the dealer, you can try disconecting the battery for a few minutes , if it is nothing serious it will reset the error code and light will be off , don't no much else about your year it is pre obd2 , ?? could be your o2 sensor went bad ?? who knows just giving you some suggestions .

Read this article: http://www.off-road.com/toyota/tech/codes/
Grab a paperclip, jumper the diagnostic connector (yours is attached to the fuseblock right behind your battery), read the flashing code. Repair as appropriate.

| When the light comes on do you notice a difference in the way it runs(accelerates/deccelerates)? If you do its probably the O2 censor. My 93 did this and i had it fixed.
My previous 85 4runner's check engine light came on and stayed on til the day i wrecked it which was many miles. I would say look for obvious things and unless you want to go have it diagnosed just ignore it.

| Stupid question, but are you sure you filled it w/ oil? The oil pressure light and check engine, I believe, will come on w/ low pressure. | |

| Is the oil filler cap on and tight? Check all the electrical and vacuum hoses in the areas of the motor where you were working to make sure you didn't accidently knock something loose.

| Did you spill oil on a sensor-namely the temp coolant sensor? It is right there to the left of the cap.

| Pull the code, reveals all secrets. My bet is on a coincidence, and it's either your TPS or your O2 sensor. Or both.

Yeah, I know, but about the only 1987 part on it anymore is the body[edit: even that ain't 1987 now...]
What is a minitruck guy doing on a Land Schmooser forum, anyway??!?!

It often takes several repetitions of an error condition before the CEL comes on. If there was no oil in the engine, it would have siezed by now.
If you can find a paperclip, you can pull the codes. It's really easy.
